Rail operators are paying increased attention to their aging IT/OT infrastructure –for good reason.
There is access control, ticketing, information kiosks and display screens. There is video surveillance to monitor footfall, support facial recognition, assist in weapons detection, and provide information for crowd control. There is Wi-Fi and mobile connectivity in stations and on trains. And, of course, there are the general alarm and warning systems, signaling and control systems, telemetry systems, dispatch systems based on TETRA / Push-To-Talk technology and not least, Communications-Based Train Control (CBTC), and supervision and monitoring systems.
Advances like these have allowed operators to increase freight and passenger capacity by adding more trains to their networks and meet growing passenger expectations by offering amenities such as Wi-Fi access on board and in stations.
